Liqui Moly Anti-Friction Oil Treatment, Twin-Pack (2) — reduces friction and protects engine components

Liqui Moly 2009 Anti-Friction Oil Treatment is a concentrated engine additive that reduces metal-on-metal contact to help lower friction and support component longevity.

This twin-pack of Liqui Moly 2009 is formulated in Germany as an aftermarket oil treatment designed to be added to your engine oil. It works with conventional and synthetic oils to improve lubrication under boundary and mixed-film conditions, aiming to smooth moving parts, reduce noise, and help protect surfaces from wear. Each pack contains two doses to treat more than one oil fill or to service multiple vehicles.

How does this additive interact with my vehicle's oil?

Liqui Moly 2009 blends with existing engine oil and forms a fine protective film on metal surfaces that can persist through normal operating temperatures. It’s compatible with most passenger car oils but always follow your vehicle manufacturer’s oil-change intervals and mixing guidance.

• Mixes into both mineral and synthetic engine oils
• Creates a lubricating layer on metal components
• Designed for use during regular oil service or as a top-up

Will using this pack reduce engine noise and stiffness?

Many users report smoother running and quieter operation after treating the oil, particularly in older or higher-mileage engines where clearances have increased. Results vary with engine condition and operating profile; allow several hundred miles for full effect as the additive disperses.

• Can ease cold-start stiffness in worn engines
• May reduce rattles and ticking caused by metal contact
• Best noticed under mixed or boundary lubrication conditions

How do I apply Liqui Moly 2009 and how often should I use it?

Application is straightforward: add the prescribed dose to the crankcase oil either at oil change or as recommended on the bottle. The pack contains two treatment doses; use one dose per specified oil volume and repeat at the next oil change if desired.

• Pour the recommended quantity into the engine oil filler
• Use one bottle per oil-change interval or per vehicle fill as directed
• Keep a spare bottle from the pack for subsequent service

What should I check before adding this product to my engine?

Confirm the additive is appropriate for your engine type and oil; check for any vehicle-specific prohibitions in your owner’s manual. If you operate high-performance or manufacturer-warranted vehicles, consult your dealer or a trusted technician to ensure compatibility.

• Verify oil compatibility and manufacturer recommendations
• Inspect seals and gaskets for pre-existing leaks
• Store unused bottles in a cool, dry place away from direct sunlight

Who is this for: Liqui Moly 2009 Anti-Friction Oil Treatment (pack of 2) is aimed at car owners, DIY enthusiasts, and independent workshops seeking a German-made oil additive to support lubrication performance and reduce metal wear. It’s especially relevant for vehicles showing early signs of wear, higher-mileage engines, or anyone wanting an aftermarket option to supplement routine oil service. It is not a substitute for scheduled maintenance; always pair use with regular oil changes and professional service when needed.
